To an wltont it 1211a co'n'cw-a: I

Be it: known that I, JOHN W. SLATER, a citizen" offthe United States, residing at Slatersvill'e, in the county of Providence and State of; Rhode Island, have invented .a new and; useful Improvement in Means for Be versing. and Controlling Interna -Combusti on "Engines, of whichthe following is a specifica-' -tion.

-'l his.invention'relates to means forreversingl and controlling,internahcombustion enand its "objects, which are threefold,

fi ovision. of means actuated by .the usual haust valves may be respectively opened and closed in manner to permit; the' crank-shaft todrive either in the forward or'reverse direc f tion at the Willfof the operator; second, the

provision of'means actuated by the usual andleverenabling. the usual inlet and-exhhu'st valves to be regulated "in'theiropera- 'tionwhether the crank shaft he driving in ;th e "forward orreversedirection; third, the revision, of v,means actuated by the usual and lever' enabling the actuation ofutheusual'ignition, device 'at such periods that the firing o'f thecharge' is'rendered effective for. in either the forward or reversev di-f cams forthei actuation of the exhaust-valve."

driving reotion'. l

In brief, my invention includes the followinginstrurnentalitiesz a half-speed shaft car'- m aya pains oppositely 'arrangedlfor the actuation. of: the inlet-valve through the m diurn Offa bipartintermediate regulating member and two correspondingly-arrange Where tw'o. or more cylinders are employer 1, each Willi-be si'milarilyequipped. Each pair crea s-are designed so that Whenturning in one direction they will operate't'he pusl1-rod or'equi'valent device for anl inlet or exhaust valveto actuate it for the admission of co m-= ,bustible gases or e'xhaustt'o-drive the crank- {shaft in the forward direction and when turning-in' the opposite direction to operate said push-rod or the'like to admit or exhaust the gases to drive the crank-shaft in the reverse direction. The bipart valve-actuating member is.--.com osed of two-pivoted operating movement. imparted to the crank-shaft beingdetermined through the timin of the oscillations, of said media, which] emselves are governed by the direction 'ofmovement of I of the valve-operating media. deta1l plan View of the cam-shaft and cams be, summarized-as follows: first, the

ltd-lever whereby the usual inlet and lex-f "mechanical elements throu the results premised. n Thus the letter A may'indicatea valve; opening of an internal-combustion cylinder;

media for t e ush rod of eachnvalve, which, 'media are osci lated in unisonby the cains "upon the half-speed shaft, the directlon of said half-speed'shaft.

In the drawings accompanyingthis application, Figaro 1 is an elevation of parts embodying my improvements shown in opera: tlve relation \shth a valve of an internal-coml Patented Ang'; 51

bustion engine. Fig. 2 isa detail plan view v Fig- 3. is a' thereon; and Figs. 4 and 5, respectively, are

perspective elevations of the two parts of which the valve actuating member is composed.

' In describingthis invention I deem it unmy improvements and have confined myself. to the'indication of a valve-opening having a valve,valve sten1,an d push-rod ,togcther with the direct intersecting parts constituting the gh which I attain necessary to illustrate a motor or the various parts thereof operat ng in COIlJllIlCt-IOD with 'but whether it be intended-as an inlet or ex haust is immaterial. the valve seated in said opening, a the valvestem, and'a a puslkrod adapted to recipro-' cate through a guide a. The push-rod a is provided with apivotal extension a;.but throughout-the specification these two parts will be referred to unitedly as the ush-rod.

Bindicates the hand-lever, w iichis fast a so fast upon said shaft, extending therethrough a pivotal link I1 Similarily, aindicates u on a rock-shaft b, an arm, as b", which is 96 from and being connected with the push-rod.

Cindicatesa shaft which is driven, as at d (1, b which they are mounted in mannerto osci late upon a pivot or shaft, as d", col-' Disposed lars, as 11 (1 serving to hold them in hinge- I like relation. The upper edges of the wings D D are conterminous and are arranged as or I provided with ways, as d d, each in form of a segment of a circle. The free end of the ush-rod, which may be provided with a "ction-ipheel, as d", abuts against and is cams 1 ch 15V adapted to travel upon these ways ass'wungsides of the eanvshal't and said tailpieees, which may he p'rovide'd \Vltlt"fl'lfitlOlI-Itllifils (1" d", are located, respectively, in' the paths of the cams e c. Said cams in their rotary action spread apart the tailpicces d (l, correspondingly drawing together the ways (P113.

The wings l) l) are shown in their normal or inoperative position by solid lines and are represented in dotted lines as rocked by the The position of the push-rod upon eitherol the ways (1" J" determines the extent of the lift to be imparted to the valve, as is evident-,smh extent being less toward the central or neutral point abo \e the" pivot d and increasing as the push-rTd is moved outwardly along a way it.v

Assuming the push-rod to be at a point intermediate the wings I) l)'namely, opposite their fulcrum or hinge-then their oscillatory action would not be communi- 'cated th the val ves;-.but if said push-rod be swung over to one side"as indicated, for example, in F 1g. 1-then the valve will ,be lifted once to every revolution of the cam-shaft,

and this lift, as well as the ignition apparatusand the various stepsol a gas-engine cycle, will be so timed that the explosion occurs when the crank-shaft isin position to receive the impulse direction. lt follows that it the push-rod be swung'in the oppositedirection the gas-en- 'gine cycle will become operative upon reversing the direction of the crank-shaft and camshaft, because-the cams will-then actuate the wing when the crank-shaft is in position to recei e thei mpulse to rotate itinthe reverse direction. l

I am aware that just prior to'moving the push-rod across the neutral point between the wings the ignition may be cut oil', compression attained, and the ignition reinstated to fire the charge at such a time that it is (ioncurrent with the proper cycle period; for either forwardor everse motion, whereby the momentum of the lly-wheel is overcome simplifies the operation as, we will say, in the forward upon these details in this application, since they belong more particularly to the province of the engineer in assembling and ad 1 justing the parts for aparticular type of en;

glue. i

One important advantage attai the use of my invention residesin the ability to throttle the engine, thereby controlling the inlet of gaseous mixture without inter through I fering with the carburetor as set for the pro duction of a suitable admixture, Another.

important advantage consists in the provision of the simple enginereversing mechan-.'- ism described, which obviates the necessity of employing the usual reversing-gearsand Having now described my invention, I d l clare that what I claim is l said push-rod, a half-speed shaft havingapair 'of'camsto oscillate saidmembers, and

means for subjeetingthe puslrrod to the in of applying the re fluence'of either of said inembers,'the oseillation of said members separately regulating the degree of lift ofthe valve and'determ'inzimparted to ing-the direction of movement the crank-shaft and cams. 1 7,; I

2. In an internal combustion engine, a

valve, a valve-stem, a push-rod therefor,

means for swaying a portionof said push-rod in opposite directions from its vertical plane,

and a valve-actuator comprising a pair of op-' pos1tely-hmged wings presenting 'umtedly' a curved way for the free end "of said push-rod,

said wings having dependent tailpieces, to-

gether with a half-speed shaft bearing a pair of oppositely-disposed cams; situate between and adapted respectively to strike the respective tailpieci-is to. thereby oscillate said wings.
